Hey, Since its drove me insane trying to figure out why my CSR was wrong, here's a reference for those who might see this in the future.
The OSRS API Error is "Invalid Field: CSR Problem: Field ''CSR'' is invalid: CSR", which is totally useless to debug, and the Geotrust site's error is "Please enter a valid CSR". Talk about vague! In my case it turned out that the two-letter ISO abbreviation in my CSR was set to "UK", whereas Geotrust wants "GB". I'm pretty sure it should be "UK"... Andy.
